The Ultra37000 family is designed to bring the flexibility, ease of use, and performance of the 22V10 to high-density CPLDs. The architecture is based on a number of logic blocks that are connected by a Programmable Inter-connect Matrix (PIM). Each logic block features its own product term array, product term allocator, and 16 macrocells. The PIM distributes signals from the logic block outputs and all input pins to the logic block inputs.All of the Ultra37000 devices are electrically erasable and In-System Reprogrammable (ISR), which simplifies both design and manufacturing flows, thereby reducing costs. The ISR feature provides the ability to reconfigure the devices without having design changes cause pinout or timing changes. The Cypress ISR function is implemented through a JTAG-compliant serial interface. Data is shifted in and out through the TDI and TDO pins, respectively. Because of the superior routability and simple timing model of the Ultra37000 devices, ISR allows users to change existing logic designs while simultaneously fixing pinout assignments and maintaining system performance.The entire family features JTAG for ISR and boundary scan, and is compatible with the PCI Local Bus specification, meeting the electrical and timing requirements. The Ultra37000 family features user programmable bus-hold capabilities on all I/Os.Ultra37000 5.0V DevicesThe Ultra37000 devices operate with a 5V supply and can support 5V or 3.3V I/O levels. V CCO connections provide the capability of interfacing to either a 5V or 3.3V bus. By connecting the V CCO pins to 5V the user insures 5V TTL levels on the outputs. If V CCO is connected to 3.3V the output levels meet 3.3V JEDEC standard CMOS levels and are 5V tolerant. These devices require 5V ISR programming.Ultra37000V 3.3V DevicesDevices operating with a 3.3V supply require 3.3V on all V CCO pins, reducing the device’s power consumption. These devices support 3.3V JEDEC standard CMOS output levels, and are 5V-tolerant. These devices allow 3.3V ISR programming.Note:1.Due to the 5V-tolerant nature of 3.3V device I/Os, the I/Os are not clamped to V CC, PCI V IH = 2V.Selection Guide5.0V Selection GuideGeneral InformationDevice Macrocells Dedicated Inputs I/O Pins Speed (t PD)Speed(f MAX) CY37032325326200 CY3706464532/646200 CY37128128564/128 6.5167 CY3719219251207.5154 CY372562565128/160/1927.5154 CY373843845160/19210118 CY375125125160/192/26410118Speed BinsDevice2001671541431251008366 CY37032X X XCY37064X X XCY37128X X XCY37192X X XCY37256 X X XCY37384X XCY37512X X XDevice-Package Offering and I/O CountDevice44-LeadTQFP44-LeadPLCC44-LeadCLCC84-LeadPLCC84-LeadCLCC100-LeadTQFP160-LeadTQFP160-LeadCQFP208-LeadPQFP208-LeadCQFP256-LeadBGA352-LeadBGACY370323737CY370643737376969CY37128696969133CY37192125CY37256133133165197CY37384165197CY37512165165197269 3.3V Selection GuideGeneral InformationDevice Macrocells Dedicated Inputs I/O Pins Speed (t PD)Speed(f MAX) CY37032V325328.5143 CY37064V64532/648.5143 CY37128V128564/80/12810125 CY37192V192512012100 CY37256V2565128/160/19212100 CY37384V3845160/1921583 CY37512V5125160/192/2641583Architecture Overview of Ultra37000 FamilyProgrammable Interconnect MatrixThe PIM consists of a completely global routing matrix for signals from I/O pins and feedbacks from the logic blocks. The PIM provides extremely robust interconnection to avoid fitting and density limitations.The inputs to the PIM consist of all I/O and dedicated input pins and all macrocell feedbacks from within the logic blocks. The number of PIM inputs increases with pin count and the number of logic blocks. The outputs from the PIM are signals routed to the appropriate logic blocks. Each logic block receives 36inputs from the PIM and their complements, allowing for 32-bit operations to be implemented in a single pass through the device. The wide number of inputs to the logic block also improves the routing capacity of the Ultra37000 family.An important feature of the PIM is its simple timing. The propa-gation delay through the PIM is accounted for in the timing specifications for each device. There is no additional delay for traveling through the PIM. In fact, all inputs travel through the PIM. As a result, there are no route-dependent timing param-eters on the Ultra37000 devices. The worst-case PIM delays are incorporated in all appropriate Ultra37000 specifications. Routing signals through the PIM is completely invisible to the user. All routing is accomplished by software—no hand routing is necessary. Warp and third-party development packages automatically route designs for the Ultra37000 family in a matter of minutes. Finally, the rich routing resources of the Ultra37000 family accommodate last minute logic changes while maintaining fixed pin assignments.Logic BlockThe logic block is the basic building block of the Ultra37000architecture. It consists of a product term array, an intelligent product-term allocator, 16 macrocells, and a number of I/O cells. The number of I/O cells varies depending on the device used. Refer to Figure 1 for the block diagram.Product Term ArrayEach logic block features a 72 x 87 programmable product term array. This array accepts 36 inputs from the PIM, which originate from macrocell feedbacks and device pins. Active LOW and active HIGH versions of each of these inputs are generated to create the full 72-input field. The 87 product terms in the array can be created from any of the 72 inputs. Of the 87 product terms, 80 are for general-purpose use for the 16 macrocells in the logic block. Four of the remaining seven product terms in the logic block are output enable (OE)product terms. Each of the OE product terms controls up to eight of the 16 macrocells and is selectable on an individual macrocell basis. In other words, each I/O cell can select between one of two OE product terms to control the output buffer. The first two of these four OE product terms are available to the upper half of the I/O macrocells in a logic block.The other two OE product terms are available to the lower half of the I/O macrocells in a logic block.The next two product terms in each logic block are dedicated asynchronous set and asynchronous reset product terms. The final product term is the product term clock. The set, reset, OE and product term clock have polarity control to realize OR functions in a single pass through the array.Speed BinsDevice 2001671541431251008366CY37032V X X CY37064V XXCY37128V XXCY37192V X X CY37256V XX CY37384V X X CY37512VXXDevice-Package Offering and I/O CountDevice 44-L e a d T Q F P 44-L e a d C L C C 48-L e a d F B G A 84-L e a d C L C C 100-L e a d T Q F P 100-L e a d F B G A 160-L e a d T Q F P 160-L e a d C Q F P 208-L e a d P Q F P 208-L e a d C Q F P 256-L e a d B G A 256-L e a d F B G A 352-L e a d B G A 400-L e a d F B G ACY37032V 3737CY37064V 3737376969CY37128V 696985133CY37192V 125CY37256V 133133165197197CY37384V 165197CY37512V165165197269269Low-Power OptionEach logic block can operate in high-speed mode for critical path performance, or in low-power mode for power conser-vation. The logic block mode is set by the user on a logic block by logic block basis. Product Term AllocatorThrough the product term allocator, software automatically distributes product terms among the 16 macrocells in the logic block as needed. A total of 80 product terms are available from the local product term array. The product term allocator provides two important capabilities without affecting perfor-mance: product term steering and product term sharing. Product Term SteeringProduct term steering is the process of assigning product terms to macrocells as needed. For example, if one macrocell requires ten product terms while another needs just three, the product term allocator will “steer” ten product terms to one macrocell and three to the other. On Ultra37000 devices,product terms are steered on an individual basis. Any number between 0 and 16 product terms can be steered to any macrocell. Note that 0 product terms is useful in cases where a particular macrocell is unused or used as an input register. Product Term SharingProduct term sharing is the process of using the same product term among multiple macrocells. For example, if more than one output has one or more product terms in its equation that are common to other outputs, those product terms are only programmed once. The Ultra37000 product term allocator allows sharing across groups of four output macrocells in avariable fashion. The software automatically takes advantage of this capability—the user does not have to intervene. Note that neither product term sharing nor product term steering have any effect on the speed of the product. All worst-case steering and sharing configurations have been incorporated in the timing specifications for the Ultra37000devices.Ultra37000 MacrocellWithin each logic block there are 16 macrocells. Macrocells can either be I/O Macrocells, which include an I/O Cell which is associated with an I/O pin, or buried Macrocells, which do not connect to an I/O. The combination of I/O Macrocells and buried Macrocells varies from device to device.Buried MacrocellFigure 2 displays the architecture of buried macrocells. The buried macrocell features a register that can be configured as combinatorial, a D flip-flop, a T flip-flop, or a level-triggered latch.The register can be asynchronously set or asynchronously reset at the logic block level with the separate set and reset product terms. Each of these product terms features program-mable polarity. This allows the registers to be set or reset based on an AND expression or an OR expression.Clocking of the register is very flexible. Four global synchronous clocks and a product term clock are available to clock the register. Furthermore, each clock features program-mable polarity so that registers can be triggered on falling as well as rising edges (see the Clocking section). Clock polarity is chosen at the logic block level.Figure 1.

The output of all buried macrocells is sent directly to the PIM regardless of its configuration. I/O MacrocellFigure 2 illustrates the architecture of the I/O macrocell. The I/O macrocell supports the same functions as the buried macrocell with the addition of I/O capability. At the output of the macrocell, a polarity control mux is available to select active LOW or active HIGH signals. This has the added advantage of allowing significant logic reduction to occur in many appli-cations.The Ultra37000 macrocell features a feedback path to the PIM separate from the I/O pin input path. This means that if the macrocell is buried (fed back internally only), the associated I/O pin can still be used as an input.Bus Hold Capabilities on all I/OsBus-hold, which is an improved version of the popular internal pull-up resistor, is a weak latch connected to the pin that does not degrade the device’s performance. As a latch, bus-hold maintains the last state of a pin when the pin is placed in a high-impedance state, thus reducing system noise in bus-interface applications. Bus-hold additionally allows unused device pins to remain unconnected on the board,which is particularly useful during prototyping as designers can route new signals to the device without cutting trace connec-tions to V CC or GND. For more information, see the application note Understanding Bus-Hold—A Feature of Cypress CPLDs .Programmable Slew Rate ControlEach output has a programmable configuration bit, which sets the output slew rate to fast or slow. For designs concerned with meeting FCC emissions standards the slow edge provides for lower system noise. For designs requiring very high perfor-mance the fast edge rate provides maximum system perfor-mance.C2C3DECODE C2C3DECODE 0123OC6C5“0” “1”1OD/T/LQRP 0123OC001OC4FEEDBACK TO PIM FEEDBACK TO PIMBLOCK RESET0−16TERMSI/O MACROCELLI/O CELLFROM PTM1OD/T/LQRP FROM PTM 1OC7FEEDBACK TO PIMBURIED MACROCELLASYNCHRONOUS PRODUCT 0−16TERMSPRODUCT C140123Q4C24C0C1C24C25C254 SYNCHRONOUS CLOCKS (CLK0,CLK1,CLK2,CLK3)1 ASYNCHRONOUS CLOCK(PTCLK)BLOCK PRESETASYNCHRONOUSFASTSLOWC26SLEW011011OE0OE1Figure 2. I/O and Buried MacrocellsClockin gEach I/O and buried macrocell has access to four synchronous clocks (CLK0, CLK1, CLK2 and CLK3) as well as an asynchronous product term clock PTCLK. Each input macrocell has access to all four synchronous clocks.Dedicated Inputs/ClocksFive pins on each member of the Ultra37000 family are desig-nated as input-only. There are two types of dedicated inputs on Ultra37000 devices: input pins and input/clock pins.Figure 3 illustrates the architecture for input pins. Four input options are available for the user: combinatorial, registered,double-registered, or latched. If a registered or latched option is selected, any one of the input clocks can be selected for control.Figure 4 illustrates the architecture for the input/clock pins.Like the input pins, input/clock pins can be combinatorial,registered, double-registered, or latched. In addition, these pins feed the clocking structures throughout the device. The clock path at the input has user-configurable polarity. Product Term ClockingIn addition to the four synchronous clocks, the Ultra37000family also has a product term clock for asynchronous clocking. Each logic block has an independent product term clock which is available to all 16 macrocells. Each product term clock also supports user configurable polarity selection.Timing ModelOne of the most important features of the Ultra37000 family is the simplicity of its timing. All delays are worst case and system performance is unaffected by the features used. Figure 5 illustrates the true timing model for the 167-MHz devices in high speed mode. For combinatorial paths, any input to any output incurs a 6.5-ns worst-case delay regardless of the amount of logic used. For synchronous systems, the input set-up time to the output macrocells for any input is 3.5 ns and the clock to output time is also 4.0 ns. These measurements are for any output and synchronous clock, regardless of the logic used.The Ultra37000 features:•No fanout delays •No expander delays•No dedicated vs. I/O pin delays •No additional delay through PIM •No penalty for using 0–16 product terms •No added delay for steering product terms •No added delay for sharing product terms •No routing delays •No output bypass delaysThe simple timing model of the Ultra37000 family eliminates unexpected performance penalties.Figure 4.

The 3.3V products meet all PCI requirements except for the output 3.3V clamp, which is in direct conflict with 5V tolerance. The Ultra37000 family’s simple and predictable timing model ensures compliance with the PCI AC specifica-tions independent of the design. IEEE 1149.1-compliant JTAGThe Ultra37000 family has an IEEE 1149.1 JTAG interface for both Boundary Scan and ISR.Boundary ScanThe Ultra37000 family supports Bypass, Sample/Preload,Extest, Idcode, and Usercode boundary scan instructions. The JTAG interface is shown in Figure 6.In-System Reprogramming (ISR)In-System Reprogramming is the combination of the capability to program or reprogram a device on-board, and the ability to support design changes without changing the system timing or device pinout. This combination means design changes during debug or field upgrades do not cause board respins.The Ultra37000 family implements ISR by providing a JTAG compliant interface for on-board programming, robust routingresources for pinout flexibility, and a simple timing model for consistent system performance.Development Software SupportWarpWarp is a state-of-the-art compiler and complete CPLD design tool. For design entry, Warp provides an IEEE-STD-1076/1164VHDL text editor, an IEEE-STD-1364 Verilog text editor, and a graphical finite state machine editor. It provides optimized synthesis and fitting by replacing basic circuits with ones pre-optimized for the target device, by implementing logic in unused memory and by perfect communication between fitting and synthesis. To facilitate design and debugging, Warp provides graphical timing simulation and analysis. Warp Professional ™Warp Professional contains several additional features. It provides an extra method of design entry with its graphical block diagram editor. It allows up to 5 ms timing simulation instead of only 2 ms. It allows comparison of waveforms before and after design changes.Warp Enterprise ™Warp Enterprise provides even more features. It provides unlimited timing simulation and source-level behavioral simulation as well as a debugger. It has the ability to generate graphical HDL blocks from HDL text. It can even generate testbenches.Warp is available for PC and UNIX platforms. Some features are not available in the UNIX version. For further information see the Warp for PC , Warp for UNIX, Warp Professional and Warp Enterprise data sheets on Cypress’s web site ().Third-Party SoftwareAlthough Warp is a complete CPLD development tool on its own, it interfaces with nearly every third party EDA tool. All major third-party software vendors provide support for the Ultra37000 family of devices. Refer to the third-party software data sheet or contact your local sales office for a list of currently supported third-party vendors.ProgrammingThere are four programming options available for Ultra37000devices. The first method is to use a PC with the 37000UltraISR programming cable and software. With this method,the ISR pins of the Ultra37000 devices are routed to a connector at the edge of the printed circuit board. The 37000UltraISR programming cable is then connected between the parallel port of the PC and this connector. A simple configu-ration file instructs the ISR software of the programming operations to be performed on each of the Ultra37000 devices in the system. The ISR software then automatically completes all of the necessary data manipulations required to accomplish the programming, reading, verifying, and other ISR functions.For more information on the Cypress ISR Interface, see the ISR Programming Kit data sheet (CY3700i).The second method for programming Ultra37000 devices is on automatic test equipment (ATE). This is accomplished through a file created by the ISR software. Check the Cypress website for the latest ISR software download information.Figure 5. Timing Model for CY37128Figure 6.

The Ultra37000 ISR software assists in this method by converting the device JEDEC maps into the ISR serial stream that contains the ISR instruction information and the addresses and data of locations to be programmed. The embedded controller then simply directs this ISR stream to the chain of Ultra37000 devices to complete the desired reconfiguring or diagnostic operations. Contact your local sales office for information on availability of this option.The fourth method for programming Ultra37000 devices is to use the same programmer that is currently being used to program F LASH370i devices.For all pinout, electrical, and timing requirements, refer to device data sheets. For ISR cable and software specifications, refer to the UltraISR kit data sheet (CY3700i).Third-Party ProgrammersAs with development software, Cypress support is available on a wide variety of third-party programmers.
